LHGG LTE Cat6 kit, Fibocom modem frequently disconnects

Hardware

Hello everyone,

I installed a MikroTik LHGG LTE Cat6 kit with a Fibocom modem at my beach house, with a SIM card from Very Mobile, an Italian connectivity provider that uses the Wind/Tre network.
Unfortunately, this device is subject to frequent connectivity drops, which are visible in the system log: https://pastebin.com/K7bsEwxF

The installation was performed with a CAT5e network cable with copper wires, approximately 20 meters long. I also thought it might be a power supply issue, but these disconnections recur even with the antenna on the workbench and the POE injector 50 cm from the system. What could it be? Any advice on how to diagnose and fix this problem, which is not serious but still annoying?

Best regards, everyone

Hi everyone,

Finally, since last night, the modem router has been unreachable (I use ZeroTier for this). It's 400 kilometers away and becomes reachable again a few minutes after 3:00 AM, when the daily nightly reboot script starts. The error is similar to the one reported; it's clear that RouterOS is alive and running underneath. Any suggestions?

Best regards, everyone...
